How to extract a portion of text from a log file
I am using Unix on Mac OS X 10.5.6.

I am trying to extract the last entry of a log (text) file. As seen below, each log entry looks like the following (date and time change with each log entry):

Quote:
==================== Carbon Copy Cloner (v. 3.1.3): 2009-01-15 01:29:59 -0500 ====================

50 - 60 lines of log entries

and ends with:

================================================================================
I want the script to extract everything quoted above, including the "===" dividers.

Currently the script I use is the following:

Code:
#! /bin/bash 
tail -n 60 /Library/Logs/CCC.log | mail -s "CCC Log" "myemailaddress"

I'm sure there is a more elegant way to extract the text I want so that I can pipe it into the mail command.

Any help you can provide would be greatly appreciated.

exigrep

EXIGREP(8)						      System Manager's Manual							EXIGREP(8)

NAME

       EXIGREP - Search Exim's main log

SYNOPSIS

       exigrep [-l] pattern [log file] ...

DESCRIPTION

       The  exigrep  utility  is  a  Perl script that searches one or more main log files for entries that match a given pattern.  When it finds a
       match, it extracts all the log entries for the relevant message, not just those that match the pattern.	Thus, exigrep can extract complete
       log entries for a given message, or all mail for a given user, or for a given host, for example.

       The -l flag means 'literal', that is, treat all characters in the pattern as standing for themselves.  Otherwise the pattern must be a Perl
       regular expression.  The pattern match is case-insensitive.  If no file names are given on the command line, the standard input is read.

       If the location of a zcat command is known from the definition of ZCAT_COMMAND in Local/Makefile, exigrep  automatically  passes  any  file
       whose name ends in COMPRESS_SUFFIX through zcat as it searches it.

BUGS

       This manual page needs a major re-work. If somebody knows better groff than us and has more experience in writing manual pages, any patches
       would be greatly appreciated.
